Algebra Word Problem #2

Please help me find the answer for this.

Alex can run 5 mph on level ground on a still day. One windy day, on which the wind blew at a consistent rate all day, he ran 11 miles on level ground with the wind and in the same amount of time ran 4 miles on level ground against the wind. What is the speed of the wind?

  • Thank you for your consistent help, Sarosh.
